Can't speak to the Flex radios -- so far, I've not lived close to one. Thanks for the link to the SM5BSZ review. Your copy of the table doesn't work very well in email, but the data in Leif's report is quite clear.

[Elecraft] K3/K2: cumulative HF xcvr review from eHam
Hope this prints OK. While doodling around today, I thought to take a look at the eHam.net product reviews. Somewhat difficult to make a lot of sense from it, so I thought I'd import it into Excel. I've limited the list below to those rigs with 100 or more reviews. The sort is by average rating, then # of reviews. Interesting stuff...and not too shabby for Elecraft K3 and K2. KUDOS. I'm happy to report that at some point in my ham career, I've owned the first 3 listed. I may regret this, but if you'd like the entire excel file, drop me a line.

I wouldn't put too much credence in a sort like this -- ratings like this are highly subjective, based on factors like expectations, intended use, relative cost, and experience and the technical background of the reviewer. Is it the guy's first rig, or has he owned and used a dozen or more over decades on the air? Is he a serious DXer, contester, or casual ragchewer? All product reviews must be read through a strong BS filter. In this particular list, for example, the TS480 is unique, being one of the first (and still few) HF rigs specifically designed for remote operation. Likewise, the 746 (I've owned two) provides a lot of bang for the buck and is fairly robust, but it's got lots of phase noise and a weak front end. The 7600 is also an RF trash generator -- clicks and phase noise abound. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3/K2: cumulative HF xcvr review from eHam
Jim, K9YC sed: [snip] I wouldn't put too much credence in a sort like this -- ratings like this are highly subjective [end snip] Which is exactly why I limited the list to 100 or more reviews. I figure that folks who buy, or might buy, a K3 or K2 (or any other rig), are probably as subjective as these reviews. Hence, increased validity overall for the average Joe Ham. If you were to review only serious contesters, I'm sure the K3 would stand out even more. But most of the reviews, by category of reviewer, are not from contesters. So I think the list is still reasonably apples to apples...but your warning is absolutely true. mx es hny! de Doug KR2Q __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Good point Eric. You demonstate how much personal interests affect how a rig might be rated. Compared to what a DX-40 has to offer the antique enthusiast, all of the rigs on Doug's list don't even make the list, Hi! 73, Ron AC7AC -Original Message- Interesting list, but I just bought a DX-40 on ebay and it's not on it.

Re: [Elecraft] K3/K2: cumulative HF xcvr review from eHam
Interesting stats, Doug. I expected the KX3 to be right up there near the top, too, but then I realized it has only 99 reviews. Just missed The Cutoff :) eHam is a highly approximate metric for radio quality. But I do read every review, since they're are often posted by customers who aren't subscribed to our reflector.

Re: [Elecraft] K3/K2: cumulative HF xcvr review from eHam
From your perspective Wayne, i'd read them all too. From my perspective as just a ham, I've pretty much given up on eHam reviews. Like me trying to learn how to pilot a helicopter, they are all over the sky. Plus, I don't know who they are, what they expected, whether or not that was realistic, or whether the actually knew what they were doing.
